CAR-UNLOADER.

Specification of Letters Patent.

Patented Aug. 15, 190 5.

Application filed December 19, 1904. Serial No. 237,55 9- To all whom, it may concern:

Beitknown that I, WALLACE P. WHITNEY, a citizen of the United States, residing at Veedersburg, in the county of Fountain and State of Indiana, have made certain new and useful Improvements in Car-Unloaders, of which the following is a specification.

My invention is an improvement in car-unloaders, having for an object to provide a novel construction whereby any material that will slidesuch, for instance, as coal, shale, grain, &c.-may be readily unloaded from a car; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a top plan View, partly broken away, of a car provided with my improvements. Fig. 2 is an end view, partly in section, of such car. Fig. 3 is a side view thereof, partly broken away, in section. Fig. 4

' is a detail view illustrating the means for closing the discharge-outlets at the ends of the car. Fig. 5 shows a somewhatdiflerent form of conveyer from that shown in the other views, and Fig. 6 illustrates a construction whereby the unloader can be arranged to unload from both ends of the car at the same time.

In carrying out my invention I provide the car A with a false floor B, which may be formed to provide as many longitudinally-extending troughs or hoppers O as there are conveyers D, of which there may be one or more, as desired, the conveyers operating in longitudinal channels E, extending along the base of the troughs C to the ends of the car, as shown. These channels E extend to the ends of the car and may be operated to discharge the load of the car at either end by use of the construction shown in Figs. 1, 2, 3, and 4:. The hopper-like troughs C are preferred, because they serve to conduct the load of the car to the channels E, in which the conveyers operate, as shown. The discharge-openings F at the ends of the car are closed, except when unloading, by any suitable devices, that shown including blocks Gr, arranged as best shown in Fig. 4: and secured on the outside by bolts or straps, so they can be dropped down and pulled out through the discharge-opening or conveyer-hole in the endgate when it is desired to unload.

Base-sections H of lengths suited to the material to be loaded and unloaded are provided to cover the conveyer-channels E,such sections H being arranged end to end, as shown in Fig. 3, and operating to cover the channels E from end to end between the blocks G.

As shownin Figs. 1, 2, and 3, the conveyer is an endless conveyer passing over suitable pulleys on shafts I, one of which may be extended beyond the side of the car and provided with a gear or sprocket wheel J, so it may be readily driven by belt-gearing or any other suitable rig arranged at the unloading point or may be turned by hand or in any other suitable manner in order to operate the conveyer to remove the material to be unloaded. Manifestly the conveyer may be of the endless form shown or of any other type-such, for instance, as ascrew-conveyer, an instance of the latter being shown in Fig. 5 of the drawings.

As before suggested, the conveyer box or channel is covered before loading with the base-sections H, and the ends of such channels or boxes are closed by the blocks G, and the material is loaded into the car. When it is desired to unload, the blocks G may be removed, and after the material over such blocks has been dragged by the conveyer the sections covering the conveyer are taken out successively as rapidly as the conveyer discharges the material over the preceding sections H, so that the conveyer is only operating upon a small portion of the material in the car and discharges the material being conveyed without any clogging and without any unusual strain upon the conveyer, as will be understood from the drawings and the foregoing description.

It will be understood the conveyer or conveyers may be extended over the ends of the car in order to dump material higher or lower or to side or sides or at any suitable distance from the car and when constructed as shown in Fig. 6 may be operated to unload from both ends of the car at the same time.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of the car having a longitudinal trough or hopper, and a conveyer box or channel extending longitudinally along the base of same, the conveyer operating in said channel or box, the sections for covering the said channel and the blocks for closing the discharge-openings at the ends of the channel or conveyer box, substantially as set forth.

2. The combination in a car-unloader with the car having a longitudinal trough-like hopper, and a conveyer box or channel at the base thereof, the conveyer operating in said box or channel, and a removable block for closing the discharge end of the box or channel, substantially as set forth.

3. The combination of a car having a pair of longitudinal troughs or hoppers, conveyer boxes or channels extending along the base of the troughs or hoppers and a conveyer having longitudinal sections moving lengthwise in'said conveyer-channels and moving in reverse directions in the opposite channels, the

conveyer having connecting portions at the ends of the car whereby the conveyer may be operated to discharge at both ends of the car at the same time, substantially as described.
